1. ^President's Address. " Canadian Geological Nomen- 

 clature." By Pt. W. Ells, LL.D. 



The paper comprised a short sketch of the origin and 

 introduction into Canadian geological literature of most of 

 the terms now employed in the description of the several 

 rock formations, found in the older or eastern provinces 

 of Canada. A brief outline is also given of some of the 

 changes of opinion which have been published from time 

 to time, by the several workers in the geological field> 

 regarding the interpretation of certain diflicult problems 

 which have arisen in this connection, and of the reasons 

 which have led thereto, with a statement of some of the 

 most recent conclusions reached from the systematic study 

 of the rocks, both in the field and laboratory. 

 2. — " Eecent Additions to the List of Injurious Insects of 

 Canada." By James Fletcher, LL.D., F.L.S. 



In 1883, Saunders's important work upon the " Insects 

 Injurious to Fruit " was published. Since that time a 

 great deal has been done in economic entomology, both as 

 to working out the life histories of crop-pests and as 

 to means of controlling many of these. . The above paper 

 treats of several injurious species which have attracted 

 public attention by their ravages upon crops of all kinds 

 for the last twenty years. 



3. — " Catalogue of Canadian Proctotrypidffi." By W. 

 Hague Harrington. 



This contribution toward a more adequate knowledge 

 of the Canadian insect faunas, consists of a list of all the 

 species in the family Proctotrypidse, which are known to 

 occur therein, but, owing to the absence of systematic 

 collecting in other localities, it is virtually limited to the 

 species obtained at Ottawa. Of the two hundred species
